The Aleph system is basically an E-series compatible set of components which will allow for building a myriad of different lights based on compatible and interchangeable parts.
The heart or center of the system is the Aleph Light Engine . The light engine when complete consists of the converter or driver and a LED packaged in a threaded assembly. In the image of prototype parts below, you can see the LED sitting on the top of the Light Engine.
The LE threads into an Aleph head. There will ultimately be three heads available as limited production parts which have been designed specifically with the LE in mind. In addition to these heads, the LE itself was designed so that it would be compatible with modified SF E series heads. An example of this is shown directly below where an E2D head was modified to accept the LE as well as a IMS so17xa reflector:
But I digress....... Coming back to the Aleph system itself, there are 3 battery tubes that were designed as part of the system but since they are interchangeable with E series style tubes, they too will go beyond the system in applications as well as other battery tubes will come into the system.
The picture below shows the three Aleph battery tubes (1x123, 1x17500 {1.5x123} & 2x123) as well as the three heads. The heads are a 1" OD with 20 mm Al reflector, the Aleph 2, a 1 1/4" OD head with 27 mm Al reflector, the Aleph 1 and a 1 3/4" OD head with 38 mm Al reflector, the Aleph 3.
These heads will all accept the same Aleph LE's and can be hosted on any of the Aleph or E series type battery tubes.
At the end of the Aleph system is the Aleph two stage tail cap, known also as the McE2S. The tail switch has its own discussion thread HERE . The Aleph two stage tail switch is a resistored switch which allows for momentary as well as constant on access of bot a low (resistored) level of light as well as full power which is dictated by the converter or driver chosen. Momentary activation is accesed by depressing the recessed rubber button at the back of the switch. Constant levels are accessed by screwing the cap further down onto the battery tube. This switch is NOT a clickie switch.
Below is a shot of the reflectors used in these Aleph heads:
EDIT: The windows used in the Aleph heads are a clear soda lime glass with Luxar AR coating on both sides. Because the Bezel ring can be adjusted to a variety of window thicknesses, other windows can be used.

Finally I got around to taking the time to get beam comparison shots between the three reflectors with the same LE used and same manyal exposure on the camera. I will post new thread but supply the beam shots here as well:
